Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Critical temperature of CO $_{2}$ is 304 K, it cannot be liquefied above 304 K

Critical temperature is the highest temperature at which gaseous state starts condensation into liquid state.

At a certain temperature, $v o l u m e \propto \frac{1}{p r e s s u r e}$ .

This is because $P V = n R T$ , so $v o l u m e = \frac{n R T}{p r e s s u r e}$

Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
